- Foam Tank: 120 liters (32 gallons)
- Pump Output: 2,000 liters/min at 145 psi
- Gross Weight: 14.1 tons (approx. 31,000 lbs)
Operational Equipment:
- Schlingmann Varus body, customized for rescue tools
- PowerShift 3 transmission
- Retarder braking system for steep gradients
- Tools for vehicle extrication and structural collapse response
Driver and Crew Safety Systems:
- Electronic Stability Program (ESP)
- Active Brake Assist
- Lane Keeping Assist
- 360-degree LED lighting and anti-slip step surfaces
The Atego HLF 10 is compact enough for dense city traffic and capable enough for rural operations.

Emergency Mobility Focus: Diesel Dominates
At RETTmobil 2025, Mercedes-Benz Special Trucks continued with diesel-based platforms, citing high reliability, fast refueling, and strong off-road capability. These vehicles operate in non-electrified areas, making current EV tech impractical for frontline service.
While electric emergency vehicles were displayed by other brands, Mercedes-Benz focused on proven drivetrain configurations.
Why These Vehicles Matter Now
Operational Relevance:
- Unimog TLF 3000 serves where infrastructure is damaged or absent.
- Atego HLF 10 delivers rapid response in cities, towns, and mixed-use areas.
Key Takeaways for Departments:
- Modular body designs make upgrades and equipment integration easier.
- Driver-assistance tech improves safety during long shifts or difficult terrain.
- Ease of maintenance through shared parts across the Mercedes-Benz truck lineup.
Final Thoughts
For emergency services, the choice of vehicle impacts mission success, crew survival, and response time. At RETTmobil 2025, Mercedes-Benz showed that it builds tools for today’s most critical scenarios—not speculative concepts.
Whether the mission is remote firefighting or urban rescue, the Unimog TLF 3000 and Atego HLF 10 bring real-world engineering to frontline service.
